Settings for Reheat only mode
During Reheat only mode, the tank setpoint can be set on the user
interface. The maximum allowed temperature is determined by the
following setting:

Comfort setpoint
Only applicable when domestic hot water preparation is
Schedule
only
or
Sc reheat
. When programming the schedule, you
can make use of the comfort setpoint as a preset value. When you
later want to change the storage setpoint, you only have to do it in
one place.
The tank will heat up until the
storage comfort temperature
has
been reached. It is the higher desired temperature when a storage
comfort action is scheduled.
Additionally, a storage stop can be programmed. This feature puts a
stop to tank heating even if the setpoint has NOT been reached.
Only program a storage stop when tank heating is absolutely
undesirable.
